TEHRAN (Tasnim) - A video has been posted on social media showing a police officer in Baytown, Texas, shooting a woman multiple times and killing her while she said she was pregnant in the Houston area city. - World news -

The woman has not been identified. The officer has also not been named and authorities have said an investigation is underway. In the video, the woman can be heard saying that she is pregnant moments before she was shot.

Police have not confirmed whether the woman who was shot was actually pregnant. The fatal shooting occurred late Monday, May 13. According to KHOU-TV's Brett Buffington, the woman was shot and killed by the officer.

Buffington reported that homicide investigators were at the scene at the apartment complex on Garth Road where the shooting occurred early Tuesday morning, May 14.

In the video, posted to Facebook and Twitter by multiple users, the woman can be heard telling the officer she is walking to her house. The officer who shot the woman appears to be the only officer at the scene during the incident. The woman can be seen walking as she tells the officer he is "harassing" her. The pop of a stun gun can be heard as the officer appears to fire his Taser at the woman. It is not clear if the stun gun hit the woman.

The woman can then be seen on the ground with the officer on top of her, trying to grab her hands. The woman yells, "I'm pregnant," and the officer steps away from her as she appears to be moving her hands near his legs. As the woman sits up, the officer fires his gun five times and the woman falls back to the ground. It is not clear how many times she was shot.

Baytown Police Lieutenant Steve Dorris said in a post on the department's Facebook page early Tuesday, "Baytown Detectives are on the scene of an Officer involved shooting in the 1600 block of Garth Road. It is very early in the investigation however what detectives have learned thus far is one of our officers, an 11 year veteran with the department, was patrolling an apartment complex in the 1600 block of Garth Road when he came across a 45-year-old female that he knew from previous encounters and knew she had outstanding warrants."

Dorris added, "The officer contacted the female and attempted to arrest her at which time a struggle ensued, forcing the officer to deploy his department issued Taser at the female. It appears that as the officer was then attempting to handcuff the female she was able to gain control of his Taser and turned it on the officer, Tasing the officer, which forced the officer to draw his duty weapon and fire multiple rounds at the female, striking her at least once."

According to Dorris, "The female has been pronounced deceased at the scene. The Harris County District Attorney's Office is on scene and assisting in the investigation, as is normal in these types of incidents. Any future updates will be provided via an official press release later today, as the investigation unfolds."

The shooting occurred at The Brixton Apartments, at 1601 Garth Road, in Baytown. The Baytown Sun reports that residents gathered at the scene Tuesday morning, along with people who said they saw the video of the shooting on social media and were angered by what they watched.
